Witnessing a Rare Atmospheric Phenomenon: Double Optical Effect in Minnesota Sky
Locals in Morris, Minnesota, were treated to a breathtaking sight on Wednesday, as a stunning double optical effect appeared in the sky. The phenomenon, known as a “sun dog” or “Parhelia,” is a rare atmospheric occurrence that has captivated the attention of sky watchers and photographers alike.
The double optical effect, which appears as two halos around the sun, is a result of sunlight passing through hexagonal ice crystals in cirrus clouds. According to the FOX Forecast Center, the sunlight must be refracted at a minimum angle of 22 degrees to produce this effect. This phenomenon is often accompanied by a slight coloration of red and blue, making it a truly mesmerizing sight.
Understanding the Science Behind the Phenomenon
The effect is known as “Parhelia,” which results from sunlight passing through hexagonal ice crystals in cirrus clouds, according to metoffice.gov. To witness a sun dog, specific atmospheric conditions must be met, including the height, depth, and position of the cirrus clouds being at a particular angle to the sun. 
The phenomenon is also referred to as a “circumzenithal arc,” or an upside-down rainbow, which requires a specific set of atmospheric conditions to occur.
Carol Bauer, who captured the phenomenon, describes it as a “circumzenithal arc,” which is a rare and breathtaking sight. The views make for a perfect photoshoot of the skyline, with the vibrant colors and unique shapes of the optical effect creating a truly unforgettable experience. As meteorological winter has already begun, the state of Minnesota has been experiencing frigid weather, making this phenomenon a rare and exciting treat for locals.
